A comprehensive comparison of photometric redshifts with MUSE DR1 redshifts was performed by [1]}. Photometric redshifts are essential ingredients for on-going and upcoming cosmological surveys (e.g., KiDS, [2]}; LSST, [3]}; Euclid, [4]}; Roman, [5]}).
Some surveys have very stringent requirement in photo-z accuracy; for example, for weak lensing, the mean redshift in each redshift bin must be constrained to better than \(2 \times 10^{-3} (1+z)\)  [6]}.
The goal of the [1]} study was to test the performance of photometric redshifts for galaxies in the Hubble Ultra Deep Field down to the 30th magnitude.
